Testing Installation
Note
Observe the following on testing after transmitter installation
to avoid damage to the human body or equipment
The equipment works on optical transmission network system in high power non- visible light
source. Keep people away from source to avoid burning skin and damage on eyes.
Clean the optical connector with high purity alcohol, waiting for the alcohol to evaporate,
Otherwise cause pollution of the equipment fiber optic interface, resulting in excessive optical
loss.
A direct optical connection cannot be made between the optical transmitter and receiver. The
connection can only be made using optical attenuators as the overall input power to the
optical receiver with the range.
Input 59 CH analog modulation signal 75dBuV/CH or digital modulation signal 68 dBµV/MHz,
according to technical specification
